Like requester chests, buffer chests can be configured to request of a specified number of up to 12 types of items from the logistic network. Logistic robots will then bring the specified items from provider chests or storage chests until the request is met. In addition, similar to a passive provider chest, any items contained in a buffer chest are made available to construction robots, logistic requests from the player, and requester chests that have the "Request from buffer chests" checkbox checked. However, items in a buffer chest are not used to fulfill requests from other buffer chests.
